UNITED STATES 'PATENT OFFICE@ LAWRENCE HEATH, OF MACEDON, ASSIGNOR OFONE-HALF TO FRANK HEATH, OF ROCHESTER, NEXV YORK.

FERTlLIZER-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 285,483, datedSeptember 25, 1883 Application filed March 16, 1883. (Nonodeh) I I TOall whom it may concern:

Be it known that I, LAWRENCE HEATH, of Macedon, Wayne county, New York,have invented certain Improvenents in Fertilizer- Distributers, of whichthe following is a specification, reference being had to the annexeddrawings.

My invention relates to certain improvenents in fertilizer-distributers,having for its object the production of a simple and cheap device forattachment to grain drills` of the ordinary Construction, by which anyof the commercial fertilizers may be regularly fed at a uniform rateinto the drill-holes when the machine is in' operation; and to this endmy invention consists in the employment, in a series of cells or ahopper attached to the drill, of rotating feed-wheels having radialfeedslides actuated by a camway, Operating in connection with astationary abutment and feedopening, to produce the above result.

My invention also consists in certain details of the apparatus, all ashereinafter more fully pointed out and specified.

My improvements in fertilizcr-distributers are represented in theaccompanying drawings, in which- 4 Figure l is a plan view. I vertedview of the feed-wheel. Fig. 3 is a section on the line x x, Fig. 1.Fig. 4 is an inverted View. Fig. 5 is a section on the line y y, Fig. l,showing` the parts to the left hand of" that line. Fig. G is a side Viewof one of the feed-slides. Fig. 7 is a section on the line z z, Fig. 1.Fig. 8 is a section on the line x' x', Fig. 1, showing the parts belowthat line, the feed-wheel and slides being onitted.

In the accompanying drawings, representing my improvedfertilizer-distributer, A is the base or botton of the cell or trough,in which the feed-wheel B revolves about a vertical aXis. The feed-wheelBis provided with the radially-movable feed-slides C C, which areoperated by the oamway L 'on the bedplate, so as to deliver thefertilizer through the opening K in the bed-plateinto a' suitable spoutor passage, through which it drops into the drill-hoe. The feedwheel Brevolves within the cell with the vertical spindle E, provided at itslower end, beneath the plate,

Fig. 2 is an in- ,be employed.

with the beveled gear F,which is operated by the pinion H on the shaftG, driven in any suitable manner from the wheel or wheels of thegrain-drill to which my improvement is applied. The shaft G revolves insuitable bearings, I, attached to the lower side of the bed-plate of themachine. The direction of rotation of the feed-wheel is indicated by thearrow in Fig. l.

The feed wheel B consists of a circular plate provided with the fiangesd and IL, in the lower edges of which are forme'd the notches e 6,'Fig.2, through which the feed-slidespass Any suitable nunber of feed-slidesC C may Each feed-slide is provided on its lower edge with a notch, i,which engages with and fits over the curved camway L,which is made ofsuch a shape that as the feed-wheel revolvcs the feedslides arewithdrawn radially, so that their outer ends come fiush with or slightlywithin the outer surface of the flange (Z while they are passing thestationary abutment J, and are afterward forced out again, asrepresented in Fig. 1. The cell or trough being filled with thefertilizeiy the projecting ends of the feed-slides Carry a portion of italong with them as the feed-wheel revolves, and deliver it through theopening K in the bottom of the trough. The abutnent J fits against theoutside of the outer fiange, d, on the feed-wheel at'Q, Fig. l. Theopening K extends from the bottom plate, A, up into the abutment to thesame level as the top of the feed-wheel. A guard, N, is fitted to theuppcr margin of the feed-wheel, being fastened to the abutnent or theside walls of the cell or trough in any suitable manner. Below the guardN the abutment is recessedout in a curve, as represented at Z, Figs. 1,7, and S, corresponding with the path described by the outer ends of thefeed-slides during this portion of the revolution of the feed-wheel. Theguard N projects slightly over`the top of the feed-wheel, preventing thei'rtilizer from falling directly into the curved recess Z, through whichthe ends of the feed-slidcs`pass.

The upper surface of the feed-wheel may be either nade flat, asrepresented in the drawings, or it may be made spherical or conical, aspreferred. In order to facilitate the IOO removal of the feed-wheel fromthe spindle E, I insert a pin or pins, z z, into the upper end of thespindle, which pius pass through the notch or notches u u in the sidesof the Opening made through the feed-wheel for the spindle, and, beingthereafterpartially rotated, come in contact with the lug or lugs v z onthe upper surface of the feed-wheel, so that' the inotion of the spiudleis thereby transnitted to the feed-wheel. This arrangenent enables theoperator to readily remove and' replace the feed-wheel.

The agitatorR may be attaehed to the upper surface of the feed-wheel,which, by it's revolution with the wheel, keeps the fertilizer in thetrough or cell stirred up, so as to facilitate its discharge by thefeed-slides.

I am aware that a horizontal roller has been provided with radiallyniovable blades extending through the same from side to side, andoperated by means of castings acting against their outer ends, and tosuch con struction I lay no clain.

It will be observed as a peculiarity of my` device that the material isdelivered down-- ward in the direction of the axis of the wheel,

instead of being delivered radially froni the wheel, as in the structureabove referred to.

I claiml. The combination, in a fertilizer-distribu- 3. The combination,in a fertilizer distributer, of the feed-wheel B, providedwith fianges dand h, a series of radially-inovable feedslides, C C, base A, abutmentJ, feed-opening K, and the supplenentary discharge-port O, substantiallyas and for the purposes described.

4. The conbnation, in a fertilizerdistributer, of the feed-wheel B,provided with a series of radially-novablefeed-slides, G C, base A,caniway L, feed-opening K, abutment J, and guard N, substantially as andfor the purposes set forth.
